Summary: Firefighter Brian Podsiadlik demonstrates how three different foam options— the Mid-Matic nozzle, FoamJet-LX, and FoamJet-MX—offer varying levels of expansion and stream control. Each nozzle setup provides tactical advantages depending on the desired foam thickness, reach, and surface coverage. The right foam tool depends on your fire type, nozzle pattern, and the expansion ratio required by your SFFF agent.
Foam isn’t one-size-fits-all — and neither are the attachments that generate it. In this quick demo, firefighter Brian Podsiadlik runs through three foam options that help you dial in exactly the right finished foam quality for the job.
The Mid-Matic nozzle is your base option for a solid foam stream. It's not technically a foam aspirator, but when used with a Class A or AFFF foam solution, it delivers a usable stream with basic air entrainment. Good for situations where you're less worried about maximum expansion and more focused on fast application with decent reach.
Next up is the FoamJet-LX, a low-expansion aspirating attachment that fits over the nozzle’s rubber bumper. It’s optimized for straight-stream use and delivers a more developed foam blanket than the Mid-Matic alone. Expect expansion ratios up to 6:1 when used with Class A or AFFF foams. This is great for vapor suppression or surface cooling without sacrificing reach.
The FoamJet-MX brings versatility to the table. This multi-expansion foam attachment works with both straight stream and fog patterns. Use straight stream when you need distance and lower expansion. Switch to fog for more air entrainment and greater expansion — ideal for blanketing surfaces or creating a thermal barrier.
Finished foam isn’t just about thickness — it’s about performance. The right expansion ratio and drain time help your foam stick, resist heat, and control flammable vapors. For example, some SFFF agents require application at a specific expansion ratio (like 7.5:1) and drain time (e.g., 20 minutes) for optimal fire suppression. Choosing the correct nozzle and foam attachment directly impacts how well your foam performs under real fireground conditions.
Mid-Matic: Quick, simple, reliable — no frills.
FoamJet-LX: Low expansion with solid reach, best for straight streams.
FoamJet-MX: Adjustable expansion, fog or straight stream compatible.
Matching your foam application to your nozzle setup is key. Whether you need reach, blanket coverage, or fuel vapor suppression, there’s a tool for it — and Podsiadlik’s demo shows exactly how they perform.
